6-2.Equilibrium-II (Ionic Equilibrium)
medium
यदि $298 \,K$ पर $PbC{l_2}$ की विलेयता $2 \times {10^{ - 2}}$ मोल$/$लीटर है, तो ${k_{sp}}$ होगा
A
$1 \times {10^{ - 7}}$
B
$3.2 \times {10^{ - 7}}$
C
$1 \times {10^{ - 5}}$
D
$3.2 \times {10^{ - 5}}$
Solution
(d) $PbC{l_2}⇌\mathop {P{b^{2 + }}}\limits_{(S)\,\,} + \mathop {2C{l^ – }}\limits_{{{(2S)}^2}} $
${K_{sp}} = 4{S^3} = 4 \times {(2 \times {10^{ – 2}})^3} = 3.2 \times {10^{ – 5}}$
